@SupportedSourceVersion(RELEASE_6) public abstract class AbstractElementVisitor6<R,P> extends Object implements ElementVisitor<R,P>
RELEASE_6
source version.WARNING: The
ElementVisitor
interface implemented by this class may have methods added to it in the future to accommodate new, currently unknown, language structures added to future versions of the Java programming language. Therefore, methods whose names begin with "visit"
may be added to this class in the future; to avoid incompatibilities, classes and subclasses which extend this class should not declare any instance methods with names beginning with "visit"
.
When such a new visit method is added, the default implementation in this class will be to directly or indirectly call the visitUnknown
method. A new abstract element visitor class will also be introduced to correspond to the new language level; this visitor will have different default behavior for the visit method in question. When a new visitor is introduced, portions of this visitor class may be deprecated, including its constructors.
